Abstract
The utility model discloses a sliding sleeve for installing a rubber ring of a piston component, which is a cylinder with a cavity arranged inside, wherein the cavity is divided into two sections, one section is a horn-shaped cavity, and the other section is a straight cylinder-shaped cavity; the diameter of the large opening of the horn-shaped cavity is larger than the outer diameter of the rubber ring; the diameter of the straight cylinder type cavity is the same as the diameter of a small opening of the horn type cavity, and the diameter of the straight cylinder type cavity is the same as the inner diameter of a cylinder body of the piston type component. The utility model provides a problem that the rubber ring blocked badly easily during the assembly.
Description
Technical Field
The utility model relates to a sliding sleeve, concretely relates to sliding sleeve that is used for piston class part rubber ring to install.
Background
In the new product development, a piston, a ring and a disc are provided with sliding components sealed by rubber rings, as shown in figure 4, the rubber rings are put into rubber ring grooves during assembly, but because the chamfer angle of a cylinder (ring) opening is very small or has no chamfer angle and the sliding clearance is very small, if the assembly force is too large or the assembly force is inclined, the rubber rings are easily damaged and are not easy to find, so that the sealing cannot be realized, and the assembly and the test fail.
SUMMERY OF THE UTILITY MODEL
The utility model provides a sliding sleeve for installation of piston class part rubber ring solves the easy problem of blocking of rubber ring when assembling.
The technical scheme of the utility model as follows:
a sliding sleeve for installing a rubber ring of a piston part is a cylinder with a cavity arranged inside, the cavity is divided into two sections, one section is a horn-shaped cavity, and the other section is a straight cylinder-shaped cavity;
the diameter of the large opening of the horn-shaped cavity is larger than the outer diameter of the rubber ring;
the diameter of the straight cylindrical cavity is the same as the diameter of a small opening of the horn-shaped cavity;
the diameter of the straight cylinder type cavity is the same as the inner diameter of the cylinder body of the piston type component.
The utility model has the advantages that:
1) the problem that the rubber ring is easy to be damaged during assembly is solved;
2) the structure is simple, economic and applicable;
3) is suitable for small-batch or single-piece trial production.

Detailed Description
Referring to fig. 1-2, a sliding sleeve for installing a rubber ring of a piston component is a cylinder 1 with a cavity arranged therein, the cavity is divided into two sections, one section is a horn-shaped cavity 2, and the other section is a straight-tube-shaped cavity 3;
the diameter of a large opening 4 of the horn-shaped cavity 2 is larger than the outer diameter of the rubber ring;
the diameter of the straight cylindrical cavity 3 is the same as that of the small opening 5 of the horn-shaped cavity;
the diameter of the straight cylinder type cavity 3 is the same as the inner diameter of the cylinder 8 of the piston type component.
As shown in fig. 1-3, during assembly, the rubber ring 7 is first installed in the rubber ring groove of the sliding disk 6 of the piston, then the sliding disk 6 is pushed in from the large opening 4 of the cylinder 1, and is slowly pushed to the port of the small opening 5, and the front end of the sliding disk 6 is introduced into the cylinder opening, so that the rubber ring 7 can be easily pushed into the cylinder body 8.
